How to Obtain and Update OCUDR MIBs For Post Software Upgrade (Doc ID 2283955.1)

Last updated on MAY 16, 2022

Applies to:

Oracle Communications User Data Repository - Version UDR 10.0.1 and later


This document provides customer instructions on how to update MIBs following OCUDR software upgrades.

Simple Network Management Protocol
Simple Network Management Protocol (SNMP) is a communication protocol that provides a method of managing TCP/IP networks, including individual network devices, and devices in aggregate. SNMP was developed by the IETF (Internet Engineering Task Force), and is applicable to any TCP/IP network, as well as other types of networks.

SNMP is an Application Program Interface (API) to the network, so that general-purpose network management programs can be easily written to work with a variety of different devices. SNMP defines a client/server relationship. The client program (called the network manager) makes virtual connections to a server program (called the SNMP agent). The SNMP agent executes on a remote network device and serves information to the manager about the status of the device. The database (referred to as the SNMP Management Information Base or MIB) is a standard set of statistical and control values that is controlled by the SNMP agent.

Through the use of private MIBs, SNMP allows the extension of the standard values with values specific to a particular agent. SNMP agents can be tailored for a myriad of specific devices such as computers, network bridges, gateways, routers, modems, and printers. The definitions of MIB variables supported by a particular agent are incorporated in descriptor files that are made available to network management client programs so that they can become aware of MIB variables and their usage. The descriptor files are written in Abstract Syntax Notation (ASN.1) format. Directives are issued by the network manager client to an SNMP agent. Directives consist of the identifiers of SNMP variables (referred to as MIB object identifiers or MIB variables), along with instructions to either get the value for the identifier or set the identifier to a new value.

The SNMP Standard
SNMP can be viewed as three distinct standards:

SNMP Message Types
Four types of SNMP messages are defined:

The four message types are all encoded into messages referred to as Protocol Data Units (PDUs), which are interchanged with SNMP devices.

Standard Managed Objects
The list of values that an object supports is referred to as the SNMP Management Information Base (MIB). MIB can be used to describe any SNMP object or portion of an SNMP hierarchy. The various SNMP values in the standard MIB are defined in RFC-1213, one of the governing
specifications for SNMP. The standard MIB includes various objects to measure and monitor IP activity, TCP activity, UDP activity, IP routes, TCP connections, interfaces, and general system description. Each of these values is associated with an official name (such as sysUpTime , which is the elapsed time since the managed device was booted) and with a numeric value expressed in dot-notation (such as '', which is the object identifier for sysUpTime).

About SNMP Configuration

SNMP configuration architecture is based on using traps to notify a network management system of events and alarms that are generated by the OCUDR application software, and those that are generated by the underlying platforms. Alarms and telemetry data are continuously collected from the entire User Data Management network and stored on the OCUDR NOAMP system. Alarms will then cause a trap to be sent as a notification of an event

Supported OCUDR MIBs

Management Information Base (MIB) contains information required to manage a product cluster and the applications it runs. The exact syntax and nature of the parameters are described in the version of each MIB that you are loading on your NMS.

At a minimum, the following MIBs must be compiled into the management station that will be receiving traps from the User Data Management systems in the network in the following order:

  1. tklc_toplevel.mib
  2. COMCOL-TC.mib
  3. UDR-MIB.mib
  4. UDR-TC.mib
  5. NET-SNMP-MIB.txt
